Final Appearance
Portrayed by

L "Mimi" Yamamoto is the grandmother of Claudia Kishi and Janine Kishi, the mother of Rioko Kishi, and the mother-in-law of John Kishi. She died in Claudia and the Sad Goodbye. During The Baby-Sitters Club series, Mimi lived with her daughter and the rest of the Kishi family on Bradford Court in Stoneybrook.


Mimi is described as quiet, patient, polite in demeanor. She has a gently rolling accent.


Mimi grew up in Japan with her older sister, parents, and her paternal grandfather. She came to the US when she was thirty-two-years-old sometime after World War II as mentioned in The Summer Before. She began living with the Kishis after her husband died and Janine was just born in Claudia and the Phantom Phone Calls.

She had a special relationship with Claudia and called her "My Claudia." Claudia often felt that Mimi was the only person in her family who understood her. It is revealed in Claudia and the Great Search that Claudia physically resembles a young Mimi. Mimi was apparently the only member of the Kishi family to appreciate Claudia's artistic talent, and once calmed told off Claudia's first-grade teacher for failing to appreciate a metaphorical self-portrait Claudia had created in The Baby-Sitters Remember.

Before she died in Claudia and the Sad Good-bye, Mimi had written her own obituary and started to label objects except for jewelry with the names of people who should inherit them. Claudia gets her jewelry, which she won't wear but will always keep.

She started to watch Wheel of Fortune daytime reruns when recovering from her stroke, previously considering it to be trash. She then got hooked on watching the show .

On Claudia's eighth birthday, Mimi dressed up in a kimono and took the family to a Japanese restaurant which turned out to be closed. Instead, they went to a sleazy pizza joint where Mimi had her first slice of pizza. She taught Mary Anne how to knit. Mary Anne invited her a first-grade tea party once before.

One time Mimi had decided to follow the ambulance when it pulled out in front of her at the grocery store. It was going to Peaches house since she had fallen down the stairs. She never followed on again.

Mimi was pulling up to an intersection and she slowed down, peered at the stoplight and glanced at Rioko and asked her what color the light was. This was when they realized that she shouldn't drive anymore.

In Kristy's Book, Kristy's first story is about a time when Kristy Thomas, Mary Anne Spier, and Claudia started a snowpeople making business for the neighbors. They raise money to get Mimi a nice birthday present. Everyone donated something to the present for her. Ms. Johnson gave them ten dollars. She mentions that Mimi checked on her everyday when she had the flu last winter. Kristy, Mary Anne, and Claudia got her a wool scarf. She wore that scarf every winter after she got it.

Health Problems[]

She recovered well; a physical therapist helped her walk and talk. She limped and couldn't use her right hand because of the stroke. Her speech was difficult.
